Lay chicken cutlets down on a working surface and spread 2 tbsp of spinach-cheese mixture on each cutlet. Loosely roll each one and keep seam side down.Dip chicken in egg mixture, then in breadcrumbs and place seam side down in a baking dish (no toothpicks needed). Repeat with the remaining chicken. When finished, lightlyspray with olive oil.

Bake 25 minutes. Remove from oven, top with sauce then cheese. Bake until cheese is melted and bubbling, about 3 more minutes. Serve with additional sauce on the side and grated cheese.
